Taiwan Region sought a more liberalized and internationalized model and opened up the construction of its free trade port area. The legal system centers on the Regulations on the Establishment of Free Trade Port Areas and is mainly based on administrative rules and supplemented by economic rules. Administrative rules are set firstly to regulate the establishment elements of the free trade port area and secondly to regulate the entry of enterprises by way of permission, featuring independent operation, but the changes in fixed assets and business still need to be approved. As for the supervision of goods, unless it is related to public safety, the entry of goods into the area will not be restricted. The activities of the goods in the area are still required to be recorded, and when leaving the area, different regulatory models are implemented according to the destination of the goods. Economic rules govern two fields of taxation and finance. As there is no material difference between the free trade ports in Taiwan Region and Hainan Province, the above legislative experience may be adopted in legislation on Hainan Free Trade Port. In fact, the Law of Free Trade Port in Hainan Province included in the legislative plan of the National People’s Congress adopts a separate legislative model featuring strengthened supervision of enterprises and goods, supplemented by economic control such as taxation and finance.
